This library contains:

  • A small specialized subset of the singletons library as it pertains to Nat and Symbol, for when you need some simple functionality without wanting to invoke the entire singletons library.
  • Operations for manipulating these singletons and KnownNat and KnownSymbol instances, such as addition and multiplication of singletons/KnownNat instances.
  • Operations for the comparison of Nats in a way that works well with GHC.TypeLits's different comparison systems. This is helpful for bridging together libraries that use different systems; this functionality is not yet provided by singletons.
